MATLAB help

Hi,

I'm new to MATLAB and programming, but I hoping to find out if I can have a variables in my program take on certain values only for certain time intervals. For example, I am using ode23s to solve some equations for me, but for the time interval [0,10] I would like one of the variables in from the equations to be 10, but from [10, 375] the variable should be 0.

Re: MATLAB help

Hi,

I am new to matlab and would be very grateful to anyone who could help. I am trying to solve a long polynomial of the third degree consisting of several terms. However the variable I want to solve for occurs both in the dominator and nominator. I was wondering how I could get all terms which involve the relevant variable onto one side of the equation to generate a simulation.
